commit 436348698f5a7539a612e147b8cb3b08baf86e6d
Author: David Smith <dsmith@redhat.com>

Fix stapiu cleanup to not hold rcu lock while decrementing semaphores.
* runtime/uprobes-inode.c (stapiu_decrement_process_semaphores): Unlock
rcu while writing semaphores. Otherwise we're atomic and we can't be in
atomic context while writing semaphores.
